Given numbers are 247, 551, 812, 508

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(247, 551) = 7163

GCD(247, 551) = ( 247 x 551 ) / 7163

= 247 / 551

= 247

Step2:

LCM(19, 812) = 15428

GCD(19, 812) = ( 19 x 812 ) / 15428

= 19 / 812

= 19

Step3:

LCM(1, 508) = 508

GCD(1, 508) = ( 1 x 508 ) / 508

= 1 / 508

= 1

So, Greatest Common Divisor of 247, 551, 812, 508 is 1
